Final Flashcards
1
Q
Enthalpy (H)
A
Heat content / the sum of the system’s internal energy
2
Q
Entropy (S)
A
A measure of randomness
3
Q
Gibbs free energy equation
A
G = H - TS
T = Temp in K
G is a measure of relative chemical stability for a phase
4
Q
Coefficient of isothermal compressibility
A
dV/dP
5
Q
Heat Capacity
A
dS/dT @ constant pressure Cp
6
Q
Effects of P and T changes
A
High P prefers low volume
High Temp favors high randomness
7
Q
Phase
A
Any homogeneous region, characterized by certain intensive properties # of region don't matter, # of kinds do
8
Q
J. Williard Gibbs (1839-1903)
A
One of the greatest American scientists of the 19th century
Provided thermodynamic foundation to much
of Physical Chemistry
9
Q
Degrees of freedom
A
The number of intensive parameters that must be specified in order to completely determine the system
10
Q
The phase rule
A
f = c - p + 2
11
Q
Unary Phase Diagrams
A
Draw
